Ubi Estate is a neighbourhood located at east-central Singapore. It lies within a somewhat rhombic piece of land bounded by Airport Road at the north, the Pan-Island Expressway at the south, Eunos Link at the east and Paya Lebar Road at the west. The area was formerly a Malay village known as Kampong Ubi.

The Malay word Ubi refers to the Tapioca plant. Coincidentally, it is the Latin word for "where" (as in "ubiquitous").

Kampong Ubi was a rather large village even for its time. The first settlements began at the junction of Jalan Ubi and Changi Road, and quickly expanded northwards to the areas designated as Ubi Estate today. All the roads and side-lanes within the kampong were named after vegetables, e.g. Jalan Kobis (cabbage), Jalan Bayam (spinach), Jalan Tauge (bean sprouts), and the like.

Today, Ubi Estate is mainly an industrial area with only the south-eastern corner developed for residential use with about 50 blocks of flats built by the Housing and Development Board. The industrial estate has a high concentration of automotive related businesses with many major dealerships having their showrooms and workshops there. Other related businesses such as body- and paint-shops also have their workshops there, along with other small and medium-sized enterprises. A few factories of multi-national firms stand alongside purpose-built flatted-factories of the Jurong Town Corporation and other private developers.
